STEAM-GENERATIN Gr SYSTEM.

Application filed February 12, 1914, Serial No. 818,355. Renewed April 27,

To all whom it may concern:

Be it known that I, FRED CARL PETERSON, a citizen of the United States, residing at Clermont, in the county of McKean and State of Pennsylvania, have invented a new and useful Steam-Generating System, of which the following is a specification.

The invention relates to improvements in steam generating systems.

The object of the present invention is to improve the construction of steam generating systems and to provide a simple and efficient construction designed for use in connection with kilns for the manufacture of sewer pipe, conduits, brick, pottery, and other clay products, and adapted to utilize the waste heat of such kilns to produce steam which may be utilized for ordinary purposes, such as running machinery, supplying steam for inside heating apparatus for drying freshly manufactured products, and the like.

With these and other objects in view, the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims appended hereto, it being understood that various changes in the form, proportion, size, and minor details of construction, Within the scope of the claims, may be resorted to without departing from the spirlt or sacrificing any of the advantages of the invention.

In the drawings: Figure 1 is a plan View of a steam generating system constructed in accordance with this invention and shown applied to a plurality of kilns. Fig. 2 is a horizontal sectional view of one of the kilns illustrating the arrangement of the steam generating coils. Fig. 3 is a vertical sectional'view of one of the kilns. Fig. 4 is an enlarged detail sectional view illustrating the manner of supporting the steam generating coils. Fig. 5 is a detail perspective view of a portion of the floor, the steam generating coil, and the supporting means therefor.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the accompanying drawings, in which is illustrated the preferred embodiment of the invention, the steam generating system comprises in its construction steam generating coils 1 designed to be mounted within kilns 2 beneath the floors 3 thereof, in order Specification of Letters Patent.

to be heated by the waste heat of such kilns. The kilns 2, which may be of any preferred number, are preferably arranged in rows, as illustrated in Fig. 1 of the drawings, and the steam generating system may be operated in connection with one or more kilns or one or more series or sections of kilns. The steam generating coils of the several kilns are connected by branch pipes 4 and 5 with line pipes 6 and 7 for supplying the steam generating coils with water and for conveying away the generated steam to one or more boilers 8 of a furnace 9. The line pipes 6 and 7 are preferably arranged between the rows of kilns and the pipe 6, which is connected with a suitable water supply, is of greater diameter than the branch pipes 4 and 5 and affords the desired water supply, and is provided at intervals opposite the spaces between the kilns with controlling valves 10, and the steam pipe or conduit 7, which is preferably arranged in parallelism with the water pipe 6, is equipped with similar controlling valves 11. By means of the valves 10 and 11 the extent of the circulation of the water and steam may be controlled, and one or more of the pairs or sets of kilns may be cut out. Also, by arranging the valves in this manner, the circulation of the water and steam is shortened when some of the kilns are not in operation, and the steam is conveyed more directly from the generating coils in use to the boilers 8. The branch pipes 4 and 5, which extend from the generating coils to the water and steam pipes 6 and 7, are provided with valves 12 and 13 for enabling any one of the kilns to be cut out when desired.

The kilns are provided with fire boxes 14 of the ordinary construction, fed from the exterior through inclined chutes 15, but the kilns with respect to such heating means, the walls, and the roof may be of any desired construction, as the heating system is designed to be applied to various constructions of kilns, as well as to kilns of the general type shown and described. The floor 3 consists of fire bricks 16 of substantially oblong form, provided at one side with a longitudinal recess 17 and arranged upon supports 18 consisting of parallel walls of brick, supported one upon another in spaced relation, as clearly illustrated in Figs. 4 and 5 of the drawings. The bricks of the spaced supports 18 are arranged in rows, the bricks of each row being spaced apart with the spaces spanned by the bricks of the next succeeding row. By this construction the floor supports or walls 18 are formed with openings 19 adapted to permit heat, smoke, and other products of combustion to pass freely through them. The fire bricks 16 span the spaces between the parallel walls or supports 18, and the recessed side edge of each brick fits against the continuous side edge of the adjacent brick, and provides an opening through the floor communicating with the intervening space between the walls or supports spanned by such brick. The openings, which are arranged at intervals throughout the entire area of the kiln floor, permit the free passage of heat and products of combustion through the floor to the spaces beneath the same, and the heat, smoke, and other products of combustion, in traveling to the chimney or stack (not shown), pass through the floor and through the parallel walls or supports 18 and escape to the chimney or stack, through a suitable flue or fines, (not shown).

The pipes 21 of the steam generating coils l are arranged horizontally and directly beneath the kiln floor, and they extend through the spaces or openings between the bricks of the top rows of the walls or supports 18. These pipes 21 preferably extend entirely across the kilns and are of sufficient number to cover the major portion of the space beneath the floor 3, but they may be of any desired number, as the particular arrangement of the bricks of the walls or supports will enable the pipes to be placed at various elevations and at various points throughout the length of the walls or supports. The Y steam generating coils are highly heated by-the fires of the kilns when the latter arein operation, and the generated steam is conducted from the steam line pipe 7 to the boilers 8 by a steam feed pipe 22 provided with a plurality of branches 23 connected with the steam domes 24 of the boilers, and provided with controlling valves 25. The steam supplied to the boilers may be utilized for various purposes, and the boilers 8 are also connected with the main water pipe 6 by a feed water pipe 26 having branches 27 connected with the boilers 8 at one end thereof. The branches 27 are pro- I vided with controlling valves 28, and the feedwater pipe is provided at a point between the series of branches and the main water pipe 6 with a controlling valve 29.

-Water and steam may be supplied to the boilers 8 of the furnace, and when the steam generating system is connected with a relativelylarge number of kilns, advantage may be taken of any of the kilns in operation and the steam generated by'the same maybe conducted to therboilers of the furnace in the most direct path, the extent of the circulation being controlled by the valves of the line pipes and the branch pipes, and any one of the kilns may be cut out of the system when desired.

No claim is made in the present application to the arrangement of the kilns, the boilers, and the pipes for connecting the same with each other and with the water supply.

What is claimed is:

l. A steam generating system including a kiln having a floor provided with apertures for the passage of the products of combustion, supports for the floor arranged at intervals and provided with apertures, and a steam generating coil located beneath the floor and having pipes extending through the apertures of the said supports and supported by the latter.

2. A steam generating system including a kiln having a floor provided with apertures for the passage of the products of combustion, spaced walls or supports arranged at intervals beneath and supporting the floor and provided with apertures for the passage of the products of combustion, and a steam generating coil having pipes arranged beneath the floor and extending through the apertures of the walls or supports and supported by the latter.

3. A steam generating system including a kiln, spaced floor supporting walls arranged at intervals and provided with apertures for the passage of the products of combustion, a floor composed of bricks spanning the spaces between the said walls and supported by the same, said floor being provided at the spaces between the walls with apertures for the passage of the products of combustion, and a steam generating coil having pipes passing through apertures of the said walls and supported by the same beneath the said floor.

4:. A steam generating system including a kiln, spaced floor supporting walls arranged at intervals, a floor composed of bricks supported at their ends upon the said walls and spanning the spaces between the same, each brick being provided at one side with a recess, the recessed side being fitted against the continuous side of the adiacent brick to form an opening at the space between the walls, and a steam generating (3011 having pipes located beneath the floor and supported by the said walls.

In testimony, that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

FRED CARL PETERSON.
